We demonstrate an optical frequency standard based on rubidium vapor loaded within a hollow-core photonic crystal fiber. We use the S1/25&\#x2192;D5/25 two-photon transition, excited with two lasers at 780 and 776&\#xA0;nm. The sum-frequency of these lasers is stabilized to this transition using modulation transfer spectroscopy, demonstrating a fractional frequency stability of 9.8&\#xD7;10&\#x2212;12 at 1&\#xA0;s. The current performance limitations are presented, along with a path to improving the performance by an order of magnitude. This technique will deliver a compact, robust standard with potential applications in commercial and industrial environments.
